Keep your doggo comfy and cool this summer with an elevated bed that keeps airflow going under furry bellies.

This classic camping lantern brings traditional vibes without the propane — it runs on four batteries and can provide up to 20 hours of light on high or 200 on the low-light setting.
This super-sleek air fryer does way more than that: Its other nine functions include making pizza, broiling, baking, toasting — and pretty much anything else you might need an auxiliary appliance for.
Made specifically for curly hair (types 3A to 4C), this top-rated hydrating shampoo has a ton of goodness to nourish curls and coils: Think honey, aloe vera, biotin, and tea tree oil for moisture and strength.
Stock up on body wash with this four-pack of Dr. Teal’s aromatherapeutic body wash — this one with eucalyptus and spearmint for a relaxing start (or end) to your day.
The O.G. Chi flat iron is mega-marked down for Prime Day. It delivers smooth, straight (or wavy!) results, thanks to settings that match the optimal temperature to your hair type.
Whether you’re roasting veg or turning out a few dozen cookies, silicone baking mats give your food a nonstick finish without extra oil or single-use parchment paper.
Ideal for renters or anyone else who could use a little no-drilling-needed storage space in their kitchen, this spice rack attaches via magnets to the side of your fridge for bonus storage that’s up and off the counter.
This compact baby food maker can chop, steam and blend so you get the homemade results you want (and trust) without a ton of effort. Cleanup is easy thanks to dishwasher-safe parts and a cleaning brush to get rogue particles off.
This Lego set is made for older teens and adults and is perfect for buying now to gift at the holidays later. 3,036 pieces make this a fun ongoing project, while the treehouse is filled with cool details like a ship in a bottle, a hand-operated crane, a bathtub and more.
Having an electric kettle on hand might be more common on the other side of the pond, but having one in your kitchen makes your nightly cup of tea super convenient to prepare — and it cuts pasta prep down a ton, too.
This set of one- and two-cup measuring vessels is great for alternating between wet and dry ingredients when you’re putting together a recipe — and they feature both ounces and milliliters so you don’t have to get out a calculator and notepad for converting.
It’s an established fact that pressure washers make grimy, otherwise labor-intensive jobs way more fun, and right now you can save about $170 on Greenworks’ version (it comes with a foam cannon, too).
Baby wipes are an essential, so when you can get them on sale, so much the better. Right now you can save 18% on 810 wipes, and they’re hypoallergenic for sensitive skin, too.
Keeping outdoor toys, patio cushions, and sports equipment organized is no mean feat, but this trunk-style box does the most when it comes to storage.
Upgrade your sleep with a whopping $2,000 off a new Casper mattress. The medium-firmness Wave Hybrid comes packed with sleep benefits, like airflow-regulating foam for cooling and super-supportive materials for those who have aches and pains (there are even gel pods under the waist and lower back).
This speaker can keep the party going indoors or outdoors, thanks to 24 hours of playtime, a ton of bass, and IPX7 waterproofing for pool parties (or unexpected rainshowers).
Kitchen storage is weirdly expensive, but this bamboo utensil organizer for silverware, paring knives, and way more is mega-marked down (especially when you clip the bonus 10% off coupon on the page). It’s expandable to fit your specific drawer size, too.
One-click will get your backyard set up for the rest of the summer — and then some, thanks to this Greenworks bundle. You’ll get a self-propelled, cordless lawn mower, leaf blower and string trimmer that makes lawn care a breeze (and, without gas, more eco-friendly, too).
Perfect rice, every time? You bet (and now for $100 off). This Zojirushi can prepare white or brown rice, rice porridge, semi-brown and sushi rice so your grain needs are totally covered — and it looks cute doing it, too.
There’s no getting around having to pick up your dog’s deposits, so you might as well stock up on bags while they’re 28% off. This set comes with a handy bag carrier, too.
You never need jumper cables until you really, really need them — so grab this set while it’s on mega-sale now so you’re prepared later.
Magnatiles don’t come cheap, so we’re loving this Lightning Deal on the dino-themed set. It comes with 40 pieces for little ones to build a prehistoric world with plus four dinos for imaginative play.
This rowing machine is a great pick for those who have their rowing routine down but would just prefer to do it from home — the bells and whistles include a TV screen with on-demand workouts (you get a month free), 26 resistance levels (plus the ability to simulate famous bodies of water), and a fold-up design for easy storage.
This commerce writer personally will not rest until every household in America is equipped with a kitchen scale. It’ll give you more precise measurements for baking, help measure out pasta, and avoid the mess of bouncing between measuring cups for washing up at the end of a kitchen project.
This 24-inch foam roller is great for sore muscles, whether they come from a long day at work or a super-intense workout.
Nothing’s worse than having to lug a wheeled cooler through the sand or, horrors, having to actually pick it up and awkwardly haul it across rough terrain. Backpack coolers are where it’s at, and this 20-can model from Coleman gives you enough space for an afternoon out for right around $40.
This handy treadmill can help you burn some calories whether you’re working or off the clock: It can convert from a walking pad for stand-up desks to a workstation you can set your laptop on to a full-fledged treadmill — all with an extremely low storage footprint, too.
This tabletop or bookshelf air purifier filters out all the smells that can accumulate in your house — as well as pet dander, dust and more. It can keep noise down to 25 decibels so you can keep it running while you sleep, too.

This walking pad can help you get your steps in while you’re checking emails at your standing desk — or while you’re chilling out with a Netflix show after work.
These sleek flipflops are great for summer’s slate of errands, kid-shuttling and days at the park — but they’ll keep your arches supported and feet cushioned as you go about your day (perfect for those dealing with arthritis and plantar fasciitis).
Perfect for light sleepers and frequent long-haul flyers, this sleep mask blocks 100% of the light coming in, plus has great details like recessed eye pockets so you can doze off without material pressing against your eyeballs. It’s also ventilated and cooling so you can rest even more easily on hot flights or warm nights.
This set of ping-pong equipment is great for basement games, backyard tournaments and afternoons at the tables in the park. It comes with four paddles, six balls and a net — meaning a full set of four players can get set up for a fiver each.
This super-cushy mat is great for the kitchen or even for a standing desk — the 24-by-70-inch space gives you plenty of room, and it’s waterproof and stain-resistant (no worries about spilled coffee) and non-slip to boot.
This portable monitor is great for those who travel a ton but need a little more screen room to get the day’s work done. The 15.6-inch display essentially doubles the visual room you get from your laptop, and it just requires one cable to set up.

Minimize food waste with this now-less-than-$50 vacuum sealer. It’ll let you divide up meat cuts, cheese, and other perishables for longer storage times, for sous-vide cooking, or for deep-freezing for a later date.
If you get out on the water a lot, be it in a kayak, sailboat, or canoe, having a dry bag that can hold your gear for the day is critical. This backpack-style one is easy to transport from the car to the boat, and it’s designed to be abrasion- and tear-resistant, too.
Garbage disposals can be pretty gross, but these fast-selling tablets help keep the stink down (especially in the summer, when the heat can make things a little more disgusting).
Get in on the cowboy boot moment that’s happening this summer for way less, with almost $50 off these highly-rated boots. They’re made from faux leather and have a slight (but walkable) heel for a little drama.
If your mattress is no longer giving you the sleep of your dreams, it might be time to intervene — and although replacing a new mattress is expensive, adding a topper is a cost-effective way to sleep a little better. This three-inch memory foam one from Dreamsmith upgrades your sleep with plush comfort and helps reduce pressure points so you can rest more easily.
This at-home rowing machine gives you a great full-body, low-impact workout whenever you want (plus it’s way less noisy for the neighbors downstairs than a treadmill). Just be sure to clip the additional $40-off coupon on the page to get the super-marked-down price.
If you didn’t get around to having a sourdough moment during the pandemic, now’s your time with 20% off everything you need to get started. This kit comes with two proofing bowls, a dough whisk, a bread scraper and everything else you need to get baking.
Boka’s toothpaste is free of all the baddies you might be looking out for — endocrine disruptors, artificial flavors and parabens — as well as fluoride. Instead, it uses nano-hydroxyapatite to help improve tooth enamel health and brighten up your teeth.
This super-connected baby monitor is great for techy parents who want to get all the metrics when it comes to their little one’s rest. You’ll get app notifications when your baby’s standing up or out of bed, crying (if you can’t hear it yourself) and sound and motion alerts, plus the app will record stats on sleep tracking, temperature and humidity, and breathing motion monitoring. There’s also two-way audio so you can check on your kid from another room.
Waterpik’s cordless water flosser makes it easy to reach the furthest corners of your mouth — and the small footprint of this model is ideal for travel or bathrooms without a lot of countertop space.
This oversized (38-by-71-inch) beach towel is great for days at the seaside or pool: It folds compactly into your suitcase, is quick to dry and won’t cling onto sand like a typical French terry towel.
This corded Waterpik has 10 settings so you get the right level of cleaning for your teeth, plus a massage mode for stimulating your gums. Seven tips are included so each member of the family can have their own — no need to buy separate Waterpiks for everyone.
